I'm aware of Battlewinner x Blister but here me out,, trust me im not insane
Glacier x Battlewinner; Glacierwinner ? Batter? Blacier?
(Lovers to Enemies essentially)
Essentially this pairing is less of a pairing within arc 1, it's basically a lovers to enemies because I think it's interesting.
Basically I imagine these two came to fall in love due to wanting to fix the connecting and hatred between the Nightwing and Icewing tribes in secret, or at-least establish a way to get Nightwings back to the mainland without any harm to others-- This was Glacier's idea. She wanted to help the Nightwings and fix their relationship as she grew to respect the tribe as opposed to fear and hate it, so sought out the help of dragons to find where the Nightwings lived. As well as them possibly being an ally in future wars and/or trades.
Long story short; They both fall in love before the beginning of the war, however Battlewinner's greed and desires to push a more dangerous and harmful into her ideas of conquering the Rainwings begins to turn Glacier somewhat against her and their relationship begins to slowly sour, before the great battle between the two tribes sparked out of a hefty debate over if taking over the rainforest was bad or not; The end result leaving Battlewinner permanently disfigured as Glacier ended up being the one to shoot frostbreath down her throat admist the battle. This is what caused Nightwings to isolate further and continue their plans in secret, as well as the continued mutual hatred for eachother both tribes possess past the war.
Battlewinner greatly despises Icewings due to this event and doesn't trust them anymore, same applies to Glacier. Battlewinner starts her alliance with Blister as a way to get back at Glacier somewhat, as well as the dragonet prophecy to push her own choice for Sandwing queen further to being reality.
